Wiltshire Police are appealing for information following an incident which happened in Amesbury this week.
In a statement they said:
"At approximately 1pm on February 2, a woman in her 80s was walking from the bus stop on London Road towards Tesco when she was approached by two women who asked for money for a charity which was raising money for deaf people.
"The woman took her purse out from her bag and handed over £10.
"During the exchange, one of the women got close to the elderly lady, who stepped back as she felt uncomfortable as a result of her demeanour.
"When she returned home, she realised that £100 was missing from her purse.
"The incident, which occurred in the covered walkway in the Tesco car park, left the woman feeling upset and embarrassed.
"The two women involved are described as white, aged in their late 20s to early 30s and they spoke with a European accent.
"Enquiries are currently ongoing."
Anyone with information should call 101 and quote crime reference number 54230011980.
